Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structure technology, and more specifically to a composite prefabricated shear wall based on the distribution of reinforcing bars according to principal stress. Background Technology
[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are used in buildings or structures to withstand horizontal loads caused by wind loads or earthquakes. Shear walls can effectively prevent building structures from being damaged by shear.
[0003] Currently, traditional prefabricated reinforced concrete shear walls have the following problems:
[0004] 1. Traditional prefabricated reinforced concrete shear walls have many vertical connecting bars, loose grouting, and high lateral stiffness;
[0005] 2. The shear wall contains a large number of small-diameter steel bars, which increases the difficulty of on-site positioning and grouting construction;
[0006] 3. Pouring concrete inside shear walls not only increases the weight of the wall but also results in poor thermal insulation.
[0007] Therefore, developing a composite prefabricated shear wall based on principal stress distribution reinforcement that can reduce lateral stiffness and improve thermal insulation and sound insulation is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0008] In view of this, the present invention provides a composite prefabricated shear wall based on principal stress distribution reinforcement, which can reduce lateral stiffness and improve thermal insulation and sound insulation effects.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A composite prefabricated shear wall based on principal stress distributed reinforcement, characterized in that it comprises:
[0011] The wall has diagonal steel bars inside, which are arranged along the direction of principal stress; the wall is filled with lightweight insulation material.
[0012] Concealed columns are provided on both sides of the wall, and the ends of the inclined steel bars extend out of the wall and into the concealed columns, where they are cast and connected.
[0013] The beneficial effects of adopting the above technical solution are that setting diagonal steel bars according to the direction of principal stress can improve the utilization efficiency of steel bars; and casting lightweight insulation material into the wall significantly reduces the self-weight of the wall, which can improve the thermal insulation and sound insulation performance.
[0014] Preferably, the wall is provided with beam ribs arranged along the principal stress direction, and the diagonal reinforcing bars are cast inside the beam ribs.
[0015] Preferably, the multiple beam ribs are distributed in a grid pattern within the wall.
[0016] Preferably, the interior of the concealed column is provided with multiple vertical reinforcing bars, and the exterior of the multiple vertical reinforcing bars is provided with multiple stirrups along their length.
[0017] Preferably, the top of the wall is connected to an upper component, and the top of the vertical steel bars and the diagonal steel bars in the top beam rib of the wall extend into the upper component and are cast and connected to the upper component.
[0018] Preferably, the bottom of the wall is connected to a lower component, and the bottom of the vertical reinforcing bars extends into the lower component and is cast-in-place with the lower component. Setting vertical reinforcing bars only in the concealed column area not only reduces construction difficulty but also decreases the overall lateral stiffness.
[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a composite prefabricated shear wall based on the distribution of reinforcing bars according to the principal stress arrangement, the beneficial effects of which are:
[0020] (1) In this utility model, the diagonal steel bars and beam ribs are arranged according to the direction of principal stress, and vertical steel bars are only set in the hidden column. The vertical steel bars are connected to the upper and lower components, which can not only improve the utilization rate of steel bars, but also reduce the lateral stiffness of the shear wall, improve the construction efficiency of the shear wall, and reduce the construction difficulty.
[0021] (2) By pouring lightweight wall materials into the wall, the self-weight of the wall and the seismic effect can be reduced, while the heat insulation, sound insulation and seismic resistance can be improved. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Concealed columns 4 are located on both sides of wall 1. The ends of the diagonal reinforcing bars 2 extend out of wall 1 and into the concealed columns 4, where they are cast and connected. The diagonal reinforcing bars 2 are distributed in a grid pattern and are arranged in multiple rows along the thickness of wall 1.
[0031] To further optimize the above technical solution, beam ribs 5 arranged along the principal stress direction are provided inside the wall 1, and diagonal reinforcing bars 2 are cast inside the beam ribs 5. The beam ribs 5 are formed by pouring concrete at the location of each diagonal reinforcing bar 2.

[0032] To further optimize the above technical solution, multiple beam ribs 5 are arranged in a grid pattern within the wall 1. Lightweight thermal insulation material 3 is filled into the grid-like cavities formed between the multiple beam ribs 5.
[0033] To further optimize the above technical solution, the lightweight insulation material poured into wall 1 is fiber-rubber granule gypsum wall material.

The preparation process of fiber-rubber granule gypsum wall material has been published in existing literature entitled "Preparation and Water Resistance Study of Fiber-Rubber Granule Gypsum Wall Material," which was published on CNKI on June 30, 2024, by Chen Kang from Shihezi University.
[0034] To further optimize the above technical solution, multiple vertical steel bars 6 are provided inside the concealed column 4, and multiple stirrups 7 are provided outside the multiple vertical steel bars 6 along their length direction.
[0035] To further optimize the above technical solution, the top of the wall 1 is connected to an upper component 8. The top of the vertical reinforcing bars 6 and the diagonal reinforcing bars 2 in the top beam rib 5 of the wall 1 extend into the upper component 8 and are cast and connected to the upper component 8. The upper component can be an upper cast-in-place floor beam.
[0036] To further optimize the above technical solution, a lower component 9 is connected to the bottom of the wall 1, and the bottom of the vertical reinforcing bar 6 extends into the lower component 9 and is cast-in-place with the lower component 9. The lower component can be a lower cast-in-place floor beam or a foundation. In this utility model, the vertical reinforcing bar 6 in the concealed column 4 is connected to the lower component 9, which can improve the construction efficiency of the shear wall and reduce its construction difficulty.
